Victoria, offer part-time childcare in Beaconsfield HP9

We have 2 children, 4 and 7. I work from home primarily Monday to Friday with occasional travel and my husband is all over the place with his work, shifts, abroad sometimes for a month. It took me a while to acknowledge I needed help with the juggle and would love some stability in the house to take some pressure off of me. I was hoping to introduce someone into our lives to help me with the children after school so I can finish my work day and not have to work all my evenings when my husband is away. I was also hoping down the line that I may be able to travel with my work and have someone here the children can feel comfortable with whilst both my husband and I are away. This would be adhoc, I would have said busier in the summer but with my husband now being away for the month of January, it is hard to say to be honest. I usually get good notice and would be able to plan ahead.
Please do not hesitate to reach out if this sounds like something you would be interested in.
I guess it is an adhoc part time nanny role, occasional evening babysitting and possibly some occasional 24/7 care in the case of both my husband and I needing to travel at the same time.
